The Republican-led Congress is increasingly writing and occasionally passing legislation to prevent President Donald Trump from taking what members believe would be ill-advised actions abroad.

The bills are few in number so far, and mostly subtle in effect. But they show how even members of Trump’s own party are restive about the commander in chief’s intentions and want to pre-empt him on multiple fronts.

This is the last week the House is in session before members depart for the August recess — expect senators to be grumbling about that.

But the House does have a fairly sizable legislative agenda before heading home through Labor Day. The highlighted legislation includes Republican-led efforts to expand and update health savings accounts and to roll back some of the taxes levied under the 2010 health care law.

Senate Armed Services Chairman John McCain has served on the committee for over three decades, helping it draft and pass dozens of National Defense Authorization Acts — some seemingly routine, others carrying historic significance.

This year’s NDAA, the annual policy bill for the Defense Department, has the potential to rank among the latter. Many provisions in the Senate version, drafted under McCain’s leadership, would have a positive long-term effect on military readiness, servicemember satisfaction and, crucially, the well-being of military families, who are often overlooked.

Now that the Singapore summit of President Donald Trump and Kim Jong Un is in the rearview mirror, major questions remain, particularly about the part of North Korea’s doomsday arsenal that Pyongyang’s military is most likely to use in a war, one that can potentially kill millions of people, and one for which the U.S. military is woefully unprepared: chemical and biological arms.

Nuclear weapons will continue to be the top concern. But they are far from the only one. Specifically, U.S. forces in the region lack sufficient medical countermeasures, protective gear and technology to identify so-called chem-bio agents, Pentagon insiders say. And the troops are insufficiently trained, manned and equipped for such a fight, according to previously unreported Pentagon audits and Army officials. Only about 1 in 3 of the Army’s special units that deal with doomsday agents is fully prepared, the service confirmed.

The massive defense authorization bill approved by the House Armed Services panel early Thursday morning is a consequential measure — but not for the reasons most people think.

The $708.1 billion bill, which the House plans to debate the week of May 21, would endorse the largest budget for defense since World War II, adjusting for inflation and when war spending is taken out of the equation.

The following seven lawmakers are a sampling of those who stand by their opposition to the deal but believe walking away from it now is a bad move that sends a signal to other countries that the U.S. is not a reliable negotiating partner. Some worry about the impact Trump’s decision could have on upcoming negotiations with North Korea over its own nuclear arsenal.

President Donald Trump announced Tuesday he would reimpose sanctions on Iran, dealing a likely fatal blow to the 2015 multinational nuclear deal and upsetting European countries, Democrats and even some Republicans.

But though Trump’s action is aimed at punishing Iran, it is anger from U.S. allies, especially France, Germany, and the United Kingdom, that could most affect the United States in the coming weeks and months.
